Yes, I've seen that one before. IMO the main problem there
is the faulty authentication system. If you put delete links
public, and fail to put proper authentication in place, someone's
going to delete your content, no matter if the delete action
is a POST submit button or a GET link.
I don't see how POST is better/more secure for a delete action.

Data-modification actions should always be made via POST, not GET, because
they're harder to make by accident that way. They can't be bookmarked or
easily picked up by spiders and search engines. GET should be used only for
read-only actions. That's what it's for (GETting data).

PHP list,
I suspect this is a rather basic concept, but I could not find the
specifics in the online manual.
I have a set of classes, and the name of each class is stored in a
column in a table in my MySQL database. When I want to create an object
from one of my classes, I also query the database to get a bunch of data
the object needs, along with its name.
So what I end up with is a variable with the name of the class that I
want to use stored as a string.
This means that I want to create an object by naming which class with
the contents of a variable:
$className = "nameFromDatabase";
$object = new $className();
Is this possible?
I hope I've asked my question clearly. Thank you for any advice.

Chris,
Thank you for replying.

Yes, it will work.
Oh, that's actually the code I can use? I just wrote it as an
explanatory aid, not thinking that it could be literally done like that.
I assumed there was a specific command I was missing.
Well, anyway, I guess I've stumbled on the right syntax. Thank you for
pointing it out to me.

For the concept of storage, you might want to look at
http://www.sitepoint.com/article/hierarchical-data-database
For a very simple implementation of the idea for display and editing,
http://www.auseinet.com/test/treeedit.php
I can provide the code for the above if you want it.
Cheers

This I had already found. But it's a very basic article, and it's not about
how to transform a set of data into a nice looking piece of HTML. It does
show some cool trees, but the display_tree function shown just uses
indents, like my own.

Thanks, but this is more or less what I have. If you can add branches to
that, I'd like to hear more.
Thank you for your answer, I appreciate it!

I know there's always RTFM, but if you would care to discuss it, I would like
to know why. How does php handle Unicode code-points and char-sets?

I need this pager fixed
http://scottishsocialnetworks.org/editorx.php
http://scottishsocialnetworks.org/editorx.php
http://scottishsocialnetworks.org/class.pager.phps
The problem is it resets when the numbered pages are pressed at the bottom.
I think the query string gets reset when the page is self submitted
I need it to page the results correctly. I can pay by paypal as soon as
someone provides (i) an agreed cost (ii) a working solution (iii) a brief
explanation.
I do not think this is a big job but I do not have enough time to fix it and
need it done asap.
thanks,

Umm..... As I said, just use file_get_contents():
$file = file_get_contents("http://www.tryout.com/1/2/";);
Assuming allow_url_fopen is on.
If not, you could try using curl - see http://www.php.net/curl
allow_url_fopen is on by default, and curl requires custom compile-time
options. Considering that, it is logical that if the user can't enable
allow_url_fopen, they're not going to be allowed to recompile PHP.

Hi Jason,
The code you pasted is littered with fatal errors and bugs (I

Production server will be PHP 5.1.2, developing on 5.0.5
I am also considering making my own 'project' object and having Folio have
an array of 'projects' rather than using the array of associative arrays.
Would this provide a solution?
Thanks,
Jason
If you're going to be using 5.1.2 in production, develop on 5.1.2. PHP
doesn't guarantee backwards compatibility, especially in such a big
change as 5.0.x -> 5.1.x. Better to develop on 5.1.2 from the start than
to develop on 5.0.5, put the code on 5.1.2, get a bunch of errors, and
then have to develop again on 5.1.2 to fix the bugs. Not to mention that
any testing done with 5.0.5 is invalid since you can't be sure that
things will behave the same with the different production version. You
may even waste time working around bugs in 5.0.5 that don't exist in 5.1.2.

I have a php form that pulls data from the database (hence the problems)
I need to do an OR search on three columns, and AND the rest, anyone
have a good way to do this? So far my searching on the MySQL lists have
been fruitless more then anything, and I figured we've probably come
across this ourselves at some point.
Here's the code I have so far:
$query = "select * from honorclub";
if ($dead != "" || $unknown != "" || $name != "" || $county != "" ||
$year != "" || $countynow != "" || $state != "")
{$query .= " WHERE ";}
if ($dead == "")
{$query .= " `Deceased`='N' AND";}
if ($unknown == "")
{$query .= " `USPS_Unknown`='N' AND ";}
if ($name != "")
{$query .= " `Last_Name` like '$name%' AND ";}
if ($county != "")
{$query .= " `County` like '$county' AND ";}
if ($year != "")
{$query .= " `Year_Tapped` like '$year' AND ";}
if ($countynow != "")
{$query .= " `County_Now` like '$countynow' AND ";}
if ($state != "")
{$query .= " `State_Now` like '$state' AND ";}
$query = rtrim($query," AND");
$query .= " order by $order_by";
What needs to be 'OR' is the $name section to be:
$query .= "`Last_Name` like '%$name%' OR `First_Name` like '%$name%' OR
`Maiden_Name` like '%$name%'";
Thanks,
Wolf

[/snip]
More of a MySQL question, but easily enough answered;
Always group the OR with parenthese and the AND individually. Write the
query and test with MySQL before placing into PHP code;
SELECT * FROM `table`
WHERE (`foo` = 'bar'
OR `foo` = 'glorp'
OR `sqirk` = 'glorp')
AND `today` = CURDATE()
AND `userID` = 'Marvin'

I'm confused just by the indenting (or lack thereof) but one standard
technique is to start off with a "yeast" such as:
$query = "select * from honorclub "; //Fix * to be actual columns!
$query .= " WHERE 1 ";
if ($dead != "" ...){
$query .= " AND Deceased = 'N' ";
}
$query .= " AND (First_name like '%$name%' or Last_name like '%$name%'
) ";

hi list,
i am facing a problem inserting binary data into a blob field.this is my

[mysqld]

connect_timeout=60
[mysql.server]
user=mysql
basedir=/var/lib
[safe_mysqld]
err-log=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
please help me. and this is what i get after running the comand mysql --help
.......................
.......................

Possible variables for option --set-variable (-O) are:
connect_timeout current value: 0
max_allowed_packet current value: 16777216
net_buffer_length current value: 16384
select_limit current value: 1000
max_join_size current value: 1000000
i guess there is some problem with connect_timeout.

I know this discussion doesn't need to continue any further..hah.. but I think
the biggest confusion people are having is that they're looking at two things
and assuming that PHP operates the same on both and these two things serve
different purposes.
1. Incrementing strings: Best example giving was "File1"++ == "File2" or
"FileA"++ == "FileB". In that case, wouldn't you want it to go from FileZ to
FileAA? Makes sense right?
2. Comparing "greatness" of strings: Rasmus mentioned this earlier, but I
wante to illustrate it a little more because I think it was overlooked. If you
have a list of names, for instance, and you alphabetize them, you'd get
something like this:
Bob
Brendan
Burt
Frank
Fred
Just become a name is longer doesn't mean it comes after the rest of the names
in the list. So in that vane, anything starting in "A" will never be >
something starting with a "Z". a < z aa < z aaa < z because:
a
aa
aaa
z
When using interation and a for loop and " <= z" it gets to "y" and it's true,
gets to "z" and it's still true, then increments to "az" and yup.. still < "z".
As mentioned, it's not until you get to something starting in "z" with
something after it that you're > "z".
So hopefully that makes a little more sense.

I thought I explained that a few times. The sequence is:
a b c ... x y z aa ab ac ... yx yy yz za zb zc ... zy zx zz aaa aab
Your loop stops at yz and doesn't get anywhere near aaa because za > z
